8 Claims. I(Cl. 20V- 4) .The present invention relates generally tothermal insulation, and more particularly to rigid bats or strips, andexible bats or strips,of thermal insulation for insertion into recesses,such as the spaces between studs or rafters.

Heretofore, insulation of this sort has been provided with mountingextensions, such as flanges, by which it is readily secured to the sidesof studs or rafters, or the faces thereof, or to both. Considerableexpense in manufacture is involved to provide such mounting means.Additionally, considerable time is required to mount the flanges.

The present invention aims to provide insulation which has a structurepermitting it to be forced into position to remain mounted betweenspaced supports.

Various other and ancillary objects and advantages of the invention willbe apparent from the following description and explanation of theinvention, given herein with reference to the accompanying drawing inwhich:

Fig. 1 shows a cross-section across a wall space I carrying split-edgeinsulation.

Fig. 2 is a horizontal sectional view' through a vertical Wall space inwhich a modied form of the invention is embodied.

Fig. 3 is a horizontal sectional "view through a vertical wall space inwhich another modified form of the invention is embodied.

Fig. 4 is a perspective view of a form of the insulation having acorrugated board facing, and toothed means carried thereby.

Fig. 5 is a perspective fragmentary view of a vertical wall structureshowing the end in crosssection in which the insulation of\ Fig. 4 ismounted.

Fig. 6 is a perspective view of a metal" device with teeth.

Fig. 7 is a perspective fragmentary view of a body insulation having alongitudinally split edge into the wings of which toothed means aremounted.

The invention may be carried out simply in a form as shown in Fig. l.The numeral lll represents a mass or body of insulation, such as afelted ber. It may be flexible or rigid, using such terms loosely andconsistently with the invention described. Numerals Il and l2 representliners, which may be paper, plain or creped, water-proofed or otherwisetreated. Numeral I3 represents a union between the material I0 and anyof the liners, for example, quilting or adhesive, such as asphalt.

The unit l0-ll-l2 has a certain degree of rigidity and of flexibility.The rigidity of the edges is subject to being increased by splitting theedges lengthwise. For example, the material I0 is cut inwardly to formtwo layers I5 and IB of it at the edges. A liner material Il is used toseal and heal this cut edge. Edge liner l'l is united to the outer sideof each liner Il and I2, and between these points, has a reverse fold i8therein lining the split in the edge of the insulation. Liner ll isshown with rectangular portions I9 over the edges of layers l5 and I6.Preferably, liner I1 is adhesively united to the liners Il and l2 andinsulation lll over its entire area. Thus, each edge of the insulationstrip may be opened. u

'Ihe width of the strip above described is greater than the width of thespace between studs 20 and 2l to receive it. The structure is so madethat it is suillciently rigid to sustain itself when placed verticallybetween studs, with the edges opened as shown to provide a substantiallytriangular space 22, which incidentally is additionally insulating. Thisforces the center of the strip to assume a position spaced from thesheathing 23 indicated in dotted lines, and from the inside Wall finish24 shown in dotted lines.-

strips such that the widths of the liner and of the mat or felt are thesame. These are preferably superimposed so that the liners will be onthe warm side of the corresponding mat. Thus in Fig. 2, the order fromcold to warm side is mat 25, liner 26, met 2l and liner 28. Mat 25 isshown completely sealed in an envelope formed by liner 26 and anadditional liner 29. Liner 29 may be a moisture barrier, but beinglargely on the cold side, it may be pervious to air or mois ture orboth. Mat 2l may be likewise completely housed in a like envelope beforesuperimposed with its companion 25. It is shown with its coldside facein part adhesively united to liner 26 by material such as asphalt 30.Asphalt 30 does The insulation may be a felt as of fibers ting the edgeof the composite structure. The non-united portion of the face iscovered by strips, one on each side, of liner material 3| Figs. 1 and 2,the split at the edge is bounded by two similar insulating layers.Structuresmay be made involving but one insulating layer. A bowingreinforcement may be used which is continuous over the insulation, oreven discontinuous.

For example in Fig. 3 spacedstuds 36, have cold-side wall finish 31 andinside Wall finish 38.

Insulation 39 is shown between studs 35. the insulationbeing notnecsarily wider than the' space between the studs 36. The insulation iscarried by one or more bowed or bowable members 40 of width greater thanthe inter-stud space. This may be a sheet of heavy cardboard withsuiiicient resiliency, or even strips of thin wood or wire or metalstrip. The choice of material or form for the bowing structure maydepend upon the weight of insulation and the in'- tended location. Sucha structure makes an excellent form for insulating inclined roofs.Ordinarily, flexible blanket in such locations sags in the center of thespan with edges mounted. Where the insulation 39 is flexible, the edges4I thereof may be tied to the bowed element 40 by a continuous web orspaced ties represented at 42. 'Ihe tie is preferably flexible so thatthe :whole structure may be made fiat to open.

Fig. 4 represents in perspective a modified form the form of Figs. 4 and5, the corrugated facing somewhat like that above described, showing an.

article as it appears in mounted position. A

Aresilient bowing back of corrugated board is Shown- This may comprise acorrugated sheet,

with lines of corrugation running across the strip sheet, or flaxible asfor rolling or installing. where a non-faced corrugated sheet is used.The insulation may be likewise flexible or rigid. Where the bowingstructure is a moisture barrier, a mat may be carried thereby, withoutany other liner, or with a moisture pervious liner at the other face.Installation may be made by pushing the unit, bowable liner rearmost,into the receiving space, until the edges of the bowing sheet 45 arewithin the studs. When lath or plaster base is applied, the insulationwill be fixed against removal. Such a mounting is shown in Fig. 5. Studs41 bear an outer-wall-lnish 48, and laths 49. A sheet of double-facedcorrugated board is coated on the face (not shown) 5| with asphalt 52 torender it moisture-vapor-transmission resistant. The asphalt is alsoused to unite any kind of mat or insulation 53 toit, such as a fiber matof mineral, anlmalor vegetable substance. Sheet 50 is wider than theinter-stud space in may have teeth permanently mounted in it, ormountable upon it in use.

Figs. 5 and 6 show a metal tooth element 55 with a bridge 5B havingteeth 5l, and legs 5I, which legs may be inserted into the edge of thecorrugated board as needed. These are shown in Fig. 4 and Fig. '5, inexaggerated appearance.

The insulation with the split edges may have toothed means as shown inFig. '1. Angular inseits 50 have one leg of the angle mounted under afacing liner 5I, with the other leg lying on the edge 52. Teeth 63 arearranged to point toward the split. Thus, the bowing causes the teeth tobite into the supports to resist closing of the flared edge. i

'Ihe invention provides insulation which may l be shipped to a job,opened from a roll or package.

and inserted without the use of a tool. Of course its success isdependent upon standard spacing of' studs, or other supports. However,such spacing is carefully maintained in general. Where conditionsrequire narrow spacing, the invention permits cutting down or othersimple alteration preserve the useful features.

It is also to be understood that the invention is not limited to brousinsulation. However, it aifords a most convenient way to adaptinsulation for easy mounting.
